This guy at my office is really superficial and doensn't think much when he opens his mouth. This is why when I can get in a good crack at him I always jump on the opprotunity. He was telling me how difficult one of his clients was being and continues by saying, "and you thought my job was easy." I responded, "I never said that, I just think you don't do a lot of it."
My boss heard me and he cracked up.
